Providing Radical Functionality to Serve Highway Transportation: A 20-Year Vision for IVHS

Individual road users face a variety of information needs that are met only in some limited way during conventional highway travel. This paper proposes the vision of a technology whose sole purpose is to improve highway travel by introducing into the system intelligent functions which deal with the limitations existing in today's “autonomous” mode of using the highway. Covered in this paper are issues that can be comprehensively addressed by Intelligent Vehicle-Highway Systems (IVHS) such as 1.) the individual driver's need for information, 2.) the individual driver's need for active assistance, 3.) communal needs for new functionality, and 4.) the whole system effects.
